Description

Technical Field

[0001] The present invention relates to the technical field of magnetization and magnetization detection, and particularly to an integrated machine for magnetization detection of multi-track incremental magnetic gratings and a magnetization method. Background Art

[0002] In the existing magnetization of magnetic gratings, when magnetizing and inkjet coding a magnetic strip or similar products, the rotating heads on both sides are rotated, and then the magnetization head magnetizes the magnetic strip.

[0003] However, due to the different lengths of magnetic strips or similar products on the market, not limited to a single track, when magnetizing some long magnetic strips and multi-track magnetizations, it is difficult for the magnetization head to complete long-distance and high-precision magnetization, and it is difficult to switch between single-track and multi-track. The magnetization effect is poor and the stability is poor. In addition, the traditional single winding structure and fixed magnetization detection device cannot magnetize and detect two different magnetic strips successively. Using the traditional magnetization structure, it is necessary to wait for the winding mechanism to wind the magnetic strip before performing magnetization detection, which prolongs the magnetization detection time and reduces the efficiency of magnetization detection.

Detailed implementation manners

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] In order to solve the technical problems mentioned in the background art, refer to the attached Figure 1 - attached Figure 10, Multi-channel incremental magnetic grating ruler magnetization detection integrated machine, including a magnetization detection frame 100. The magnetization detection frame 100 includes a magnetization detection chamber 120 and winding chambers 110 located on both sides of the magnetization detection chamber 120. A magnetization detection device is arranged in the magnetization detection chamber 120, and winding devices 200 are arranged in the two winding chambers 110. During the magnetization detection of the magnetization strip 600, the winding device 200 winds the magnetization strip 600 to control the directional movement of the magnetization strip 600. The magnetization and detection of the magnetization strip 600 are realized through the magnetization detection device. During the magnetization detection process, the magnetization strip 600 is stationary, and the magnetization and detection of the magnetization strip 600 are completed during the directional movement of the magnetization detection device; after the magnetization detection of this section of the magnetization strip 600 is completed, the winding device 200 is controlled to complete the winding of the magnetization strip 600, and the unmagnetized part is conveyed into the magnetization detection chamber 120 to complete continuous magnetization detection.

[0031] The winding device 200 includes two winding components 210 arranged at intervals. The directional winding of the magnetization strip 600 is completed through the winding components 210. Two magnetic strip bases 300 are also arranged inside the magnetization detection chamber 120. The two magnetic strip bases 300 respectively face the corresponding winding components 210 to form two magnetization detection channels for the magnetization strip 600 to pass through.

[0032] According to the different positions of the two winding devices 200, the two magnetization detection channels can be arranged at intervals in the same inclined plane as shown in the figure; the two magnetization detection channels can also be located in the same vertical platform. The magnetization detection device is controlled to move to different positions to face different magnetization strips 600 to complete the magnetization detection of different magnetization strips 600; the two magnetic strip bases 300 are controlled to be opposite in planes at different heights.

[0033] Specifically, the magnetization detection device includes a magnetic grating ruler magnetization main body 400 and a driving device 500 for driving the magnetic grating ruler magnetization main body 400 to move. Through the driving device 500, the magnetic grating ruler magnetization main body 400 can be controlled to move along the length direction or the width direction of the magnetization strip 600.

[0034] The magnetic grating ruler magnetization main body 400 includes a magnetization end 410, a detection head 420, and an inkjet printer 430 arranged in parallel. The magnetic grating ruler magnetization main body 400 further includes a rotary drive joint 451 for controlling the synchronous deflection of the magnetization end 410, the detection head 420, and the inkjet printer 430 by 180°. Through the rotary drive joint 451, the magnetization detection structure of the magnetic grating ruler magnetization main body 400 can be deflected by 180° for upward or downward deflection control, which can be applied to the control in the scenario where the magnetization detection channels are at different heights. The magnetization end 410 is internally provided with a fine adjustment mechanism 412 for controlling the telescopic movement of the magnetization end 410. Through the fine adjustment mechanism 412, the position of the magnetization end 410 can be finely adjusted and can move relative to the width direction of the magnetization strip 600, so as to realize the magnetization and detection of different code tracks on the surface of the magnetization strip 600.

[0035] It should be noted that after the magnetization end 410, the detection head 420, and the inkjet printer 430 are deflected by 180°, the relative positions of the three change. Here, the magnetization end 410 can always be in the front direction to complete the magnetization and detection of the two magnetization strips 600.

[0036] Refer to the attached Figure 3 , for example: during the process of the magnetic grating ruler magnetization main body 400 moving from left to right as a whole, the magnetization end 410 is at the rightmost position to complete the magnetization and detection of the magnetic strip base 300 at the lower end.

[0037] After the magnetic grating ruler magnetization main body 400 moves to the extreme rightmost position, control the magnetization end 410, the detection head 420, and the inkjet printer 430 to deflect by 180°. At this time, the orientations of the three are opposite, and the magnetization end 410 is at the leftmost position. At this time, the magnetic grating ruler magnetization main body 400 moves as a whole from right to the left direction to complete the magnetization and detection of the magnetic strip base 300 at the upper end.

[0038] Repeat the above steps to complete the continuous magnetization and detection of the two magnetization strips 600. During the continuous detection process, there is no need to wait, realizing continuous and efficient magnetization and detection.

[0039] The driving device 500 here includes an electric guide rail 540. Through the electric guide rail 540, the driving device 500 and the magnetic grating ruler magnetization main body 400 as a whole can be controlled to move along the width direction of the magnetization strip 600, so as to realize the adaptive magnetization detection of the two magnetization strips 600 in the same inclined plane.

[0040] In summary, through the above structural design, two winding components 210 can be used to individually control the winding of two magnetizing strips 600. By controlling the magneto - grating ruler magnetizing main body 400 to face different magnetizing strips 600, continuous magnetizing detection of the two magnetizing strips 600 can be completed, shortening the winding waiting time existing in traditional magnetizing detection equipment. And through the fine - tuning mechanism 412, the telescopic position of the magnetizing end 410 can be adjusted and controlled to achieve magnetizing and detection of multiple code tracks on the surface of the magnetizing strip 600. The improved structure can conveniently realize the switching between single - code track and multiple - code track, with good magnetizing effect and good stability. At the same time, without waiting for the winding time of the magnetizing strip, the magneto - grating ruler magnetizing main body 400 completes continuous magnetizing detection of different magnetizing strips 600 during the reciprocating movement, shortening the magnetizing detection time and greatly improving the efficiency of magnetizing detection.

[0041] Specifically, the winding component 210 includes two winding wheels 211 and several groups of guide wheels 212. During the synchronous rotation of the two winding wheels 211, continuous winding of the magnetizing strip 600 is completed. Under the action of the guide wheels 212, the magnetizing strip 600 is in a horizontal or bent state at different positions, ensuring the normal winding, magnetizing and detection of the magnetizing strip 600. The winding wheel 211 rotates in a fixed direction to complete the winding of the magnetizing strip 600.

[0042] A limiting groove for the magnetizing strip 600 to pass through is opened on the side wall of the magnetic strip base 300. The magnetizing strip 600 can be located in the limiting groove for limiting, ensuring the stability of the magnetizing strip 600 during the magnetizing process. A first cooling pipeline through which a first cooling medium passes is embedded inside the magnetic strip base 300. Controlling the directional flow of the first cooling medium in the first cooling pipeline can absorb and carry away the heat generated during the magnetizing process, realizing efficient heat dissipation of the entire magnetic strip base 300.

[0043] A second cooling pipeline through which a second cooling medium passes is arranged inside the magneto - grating ruler magnetizing main body 400. Similarly, during the directional flow, the second cooling medium can carry away the heat around the magneto - grating ruler magnetizing main body 400, maintaining the temperature around the magneto - grating ruler magnetizing main body 400 within a suitable range. Here, the second cooling pipeline is embedded inside the magneto - grating ruler magnetizing main body 400 and abuts against the main heating elements to complete efficient liquid - cooling heat dissipation.

[0044] The driving device 500 includes a relatively fixed support base 510, a relatively movable driving end 520, and a left - right moving member 530 for controlling the relative movement of the driving end 520 relative to the support base 510. The above - mentioned left - right moving member 530 selects an existing driving structure and can control the driving end 520 to linearly move along the length direction of the magnetizing strip 600. The entire magneto - grating ruler magnetizing main body 400 is detachably fixed to the outer surface of the driving end 520 and can move synchronously.

[0045] An accommodation chamber 511 is formed inside the support base 510. A pumping device 800 for pumping the first cooling medium and the second cooling medium is arranged inside the accommodation chamber 511. During the linear movement of the driving end 520, the pumping device 800 is driven to act synchronously to complete the pumping of the first cooling medium and the second cooling medium. During the movement of the driving end 520, the pumping of the first cooling medium and the second cooling medium is automatically completed without separately arranging pumping elements and sensing elements for separate control, simplifying the control process and improving the pumping efficiency.

[0046] Specifically, the pumping device 800 includes two symmetrically arranged pumping bases 820. The pumping base 820 includes a pumping housing 821. A pumping piston 822 is hermetically and slidably connected to the inner wall of the pumping housing 821. A pumping rod 810 is fixed between the two pumping pistons 822. The pumping housing 821 is divided into a first pumping chamber 8001 and a second pumping chamber 8002 by the pumping piston 822. The first pumping chamber 8001 and the second pumping chamber 8002 are used to accommodate the cooling medium. During the reciprocating movement of the pumping piston 822, the extraction and pumping of the cooling medium are completed.

[0047] Two pumping pipes 823 with built-in one-way valves are connected to both the first pumping chamber 8001 and the second pumping chamber 8002. One pumping pipe 823 of the first pumping chamber 8001 is connected to the first cooling pipe, and one pumping pipe 823 of the second pumping chamber 8002 is connected to the second cooling pipe.

[0048] During the reciprocating movement of the pumping rod 810, the two second pumping chambers 8002 alternately pump the second cooling medium, realizing continuous cooling of the end of the magneto - grating charging main body 400. At the same time, the first pumping chambers 8001 on both sides alternately pump the cooling medium into the corresponding first cooling pipes, realizing alternating cooling of the two magnetizing bars 600. Through the above - mentioned structural design, continuous cooling of the magneto - grating charging main body 400 and alternating cooling of the two magnetizing bars 600 can be just realized, and precise pumping of the two cooling media can be achieved.

[0049] As shown in the Figure 9 accompanying figure. During the upward movement of the lower pumping piston 822, the first pumping chamber 8001 expands and the second pumping chamber 8002 shrinks. Under the action of the one - way valve, the first pumping chamber 8001 here can complete the extraction of the cooling medium, and the second pumping chamber 8002 here can complete the pumping of the cooling medium.

[0050] During the downward movement of the pumping piston 822, their action processes are opposite. During the synchronous reciprocating movement of the pumping piston 822 with the driving end 520, continuous pumping of the two cooling media is completed.

[0051] A clutch device 700 is provided between the driving end 520 and the pumping rod 810, and the connection state between the pumping rod 810 and the driving end 520 is adjusted by the clutch device 700. Temperature sensing elements are provided in the first cooling pipe and the second cooling pipe, and the two temperature sensing elements are electrically connected to the clutch device 700.

[0052] Through the above structural design, the pumping state of the cooling medium can be adjusted according to the temperature change of the cooling medium. After the temperature of any cooling medium rises above a threshold, the clutch device 700 is controlled to be in a connected state, so that the pumping of two cooling media can be achieved.

[0053] The clutch device 700 is controlled to be in a disengaged state, and the driving terminal 520 is controlled to be separated from the pumping rod 810. The driving terminal 520 will not drive the pumping rod 810 to move synchronously during the reciprocating movement, and will not complete the pumping of the cooling medium, thereby reducing the overall load and achieving precise pumping heat dissipation.

[0054] As a first embodiment of the clutch device 700, the clutch device 700 includes a positioning ring 710 fixedly connected to the pumping rod 810, and also includes a telescopic clutch 720 that is telescopic and located on the moving path of the positioning ring 710. A positioning protrusion 711 adapted to the telescopic clutch 720 is fixed to the side wall of the positioning ring 710.

[0055] The telescopic clutch 720 is controlled to extend. At this time, the telescopic clutch 720 is located on the moving path of the positioning protrusion 711. During the movement of the telescopic clutch 720, the positioning ring 710 and the pumping rod 810 can be driven to move synchronously under the action of extrusion to realize the pumping of the cooling medium.

[0056] When the moving path of the driving end 520 is long, the telescopic clutch 720 can be controlled to shrink and stagger with the positioning protrusion 711, and the telescopic clutch 720 can continue to move with the driving end 520, and the positioning ring 710 stays at the original position without external force and does not change.

[0057] The telescopic change of the telescopic clutch 720 after it moves to the extreme position is controlled by the central processing unit and the position sensing element in a coordinated manner to avoid collision and extrusion between the telescopic clutch 720 and the positioning ring 710 to cause local damage.

[0058] As a second embodiment of the clutch device 700, the clutch device 700 includes a connecting capsule arranged between the pumping rod 810 and the driving end 520. The connecting capsule is in the shape of an elongated strip and is filled with electrorheological fluid. A control power supply electrically connected to the temperature sensing element is arranged inside the connecting capsule.

[0059] When the temperature sensing element senses that the temperature exceeds the set threshold, the electrorheological fluid is controlled by the control power supply to conduct electricity and be in a solid state. During this process, when the driving end 520 moves, the middle solid connecting bladder drives the inner pumping rod 810 to move synchronously, realizing the pumping of the cooling medium.

[0060] When the temperature sensing element senses that the temperature is lower than the set threshold, the electrorheological fluid is controlled by the control power supply to cut off the power and be in a liquid state. During this process, the movement of the driving end 520 will not drive the inner pumping rod 810 to move synchronously, notifying the pumping of the cooling medium.

[0061] Through the above structural design, during the process of the driving end 520 moving from the leftmost position towards the right, it can drive the pumping rod 810 located in the middle to move synchronously at any time, and can complete the pumping of the cooling medium at any time; at the same time, when the pumping rod 810 moves to the limit position, it is detected by the position sensing element, and the electrorheological fluid is timely controlled to be in a power-off state to avoid damage to the internal structure.

[0062] Specifically, the magneto - grating ruler magnetization main body 400 includes a first installation platform 440 and a second installation platform 450. The second installation platform 450 is arranged between the magnetization end 410 and the first installation platform 440. A linear driving joint 441 is arranged between the first installation platform 440 and the driving device 500, and a rotary driving joint 451 is arranged between the first installation platform 440 and the second installation platform 450.

[0063] During the driving control process, through the rotary driving joint 451, the second installation platform 450 can be controlled to drive the outer magnetization end 410 and other structures to deflect by 180°, completing the driving control; and through the first mounting seat 411, the first installation platform 440 can be driven to move linearly up and down, so that the magnetization end 410 can approach or move away from the corresponding magnetization strip 600, ensuring the normal deflection of the overall magnetization end 410 and completing the effective magnetization and detection of the magnetization strip 600, ensuring the normal operation of the overall structure and meeting the control requirements in multiple situations.

[0064] It should be noted that the magnetization end 410 here includes structures such as a first mounting seat 411, a fine - tuning mechanism 412, a magnetization head 413, and a second mounting seat 414. The second mounting seat 414 is fixedly connected to the inner second installation platform 450. Under the action of the fine - tuning mechanism 412, the first mounting seat 411 can move linearly along the direction perpendicular to the surface of the second installation platform 450. And the magnetization head 413 here is detachably installed on the outer surface of the first mounting seat 411. The fine - tuning mechanism 412 is symmetrically arranged in two groups to control the stability of the first mounting seat 411 during the movement along the direction perpendicular to the width direction of the magnetization strip 600 (the direction perpendicular to the surface of the second installation platform 450).

[0065] The present invention will be further described below in conjunction with the magnetization detection method.

[0066] The magnetization detection method for a multi-track incremental magnetic grating scale uses the above-mentioned multi-track incremental magnetic grating scale magnetization detection all-in-one machine, and includes the following steps:

[0067] S1. Control the magnetic grating scale magnetization main body 400 to face the magnetization strip 600 in the first magnetic strip base 300, and control the magnetic grating scale magnetization main body 400 to move from the first side towards the second side through the driving device 500. During the process of the magnetic grating scale magnetization main body 400 moving from the first side towards the second side, the magnetization and detection of the magnetization strip 600 in the first magnetic strip base 300 are completed; for Figure 3 example, the magnetic grating scale magnetization main body 400 moves from the left side towards the right side to complete the magnetization and detection of the magnetization strip 600 in the bottom magnetic strip base 300.

[0068] S2. Control the magnetic grating scale magnetization main body 400 to deflect 180° and then face the magnetization strip 600 in the second magnetic strip base 300, and control the magnetic grating scale magnetization main body 400 to move from the second side towards the first side through the driving device 500. During the process of the magnetic grating scale magnetization main body 400 moving from the second side towards the first side, the magnetization and detection of the magnetization strip 600 in the second magnetic strip base 300 are completed; for Figure 3 example, the deflected magnetic grating scale magnetization main body 400 moves from the right side towards the left side to complete the magnetization and detection of the magnetization strip 600 in the top magnetic strip base 300.

[0069] Among them, during the magnetization detection process, the multi-track magnetization is completed by controlling the telescopic movement of the magnetization end 410 through the fine adjustment mechanism 412. After the magnetization of the magnetization strip 600 is completed, the winding of the magnetization strip 600 is completed through the corresponding winding assembly 210; repeat the above steps to complete the continuous magnetization detection of the two magnetization strips 600.

[0070] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
